In a span of ten years, more than 6000 potentially new species have been discovered in this global effort to determine the extent of biodiversity in our oceans.

It seems there is no limit to the extreme environments these strange, brave creatures call home. Many nooks and crannies of our oceans are occupied – including rocky seamount slopes, deep ocean trenches devoid of light,
